AbstractAbstract PDF
Familial isolated primary hyperparathyroidism(FIPH) is associated with multiple endocrine neoplasia type 1 (MEN1) syndrome, primary hyperparathyroidism accompanied by jaw-tumor syndrome, and familial hypocalciuric hypercalcemia. FIPH may be an early stage of MEN1 or an allelic variant of MEN1. Thymic carcinoid tumor is a rare tumor in MEN1 syndrome. Here, the authors report the case of a 40-year-old man diagnosed with recurrent thymic carcinoid tumor and FIPH. Both the patient and his elder sister had been previously diagnosed to have FIPH with a novel frameshift mutation in the MEN1 gene. Initially, the patient underwent thymectomy because of an incidental finding of a mediastinal mass in his chest X-ray, and had remained asymptomatic over the following 4 years. Pancreas computed tomography conducted to evaluate MEN1 syndrome revealed anterior and middle mediastinal masses, and resultantly, massive mass excision was performed. Histological findings disclosed atypical carcinoids with infiltrative margins. In view of the thymic carcinoid tumor relapse that occurred in this patient, the authors recommend that regular pancreas and pituitary imaging studies be conducted for FIPH associated with a MEN1 gene mutation.

AbstractAbstract PDF
Primary thyroid lymphoma is a relatively rare thyroid tumor and usually a non-Hodgkin type. Its most common histologic type is the diffuse large B cell lymphoma followed by mucosa-associated lymphoid tissue (MALT). It is known to be frequently associated with autoimmune thyroiditis such as Hashimoto's thyroiditis. We report three cases of thyroid lymphoma at a single institution with a review of the literature.

AbstractAbstract PDF
The incidence of coexisting hyperparathyroidism and empty sella syndrome is rare and the etiology and incidence of their coexistence is not known. The association of hyperparathyroidism and the empty sella syndrome may be related to multiple endocrine neoplasia (MEN) syndrome due to a genetic disorder. We experienced a rare case of hyperparathyroidism presenting as acute pancreatitis combined with empty sella. We report here a 37-year old female who manifested epigastric pain because of acute pancreatitis. She had hypercalcemia due to parathyroid adenoma. A pituitary gland was not visible in the sella turcica on MRI scans. On genetic analysis, she did not show a mutation of the MENIN gene. Empty sella is thought to be a coincidental finding with hyperparathyroidism.
